The purpose of this report is to present conservative treatment for two immature premolars with apical periodontitis. A triple antibiotic paste was used to disinfect the root canal systems for revascularization. In both cases, residual vital pulp tissue was noted in the root canal system after the opening of each premolar. The canals in both cases were irrigated with copious sodium hypochlorite solution and medicated with a paste consisting of ciprofloxacin, metronidazole, and minocycline. The teeth were sealed with mineral trioxide aggregate and restored with composite resin. There were satisfactory outcomes after 18 months. The patients were asymptomatic, with radiographic evidence of complete resolution of radiolucency, continual thickening of dentinal walls, apical closure, and increased root length.
本报告旨在介绍对两颗患有根尖周炎的未成熟前磨牙的保守治疗。使用三联抗生素糊剂对根管系统进行消毒以促进血管再生。在这两个病例中，每颗前磨牙开髓后，根管系统中均发现有残留的活髓组织。两例病例的根管均用大量次氯酸钠溶液冲洗，并用含环丙沙星、甲硝唑和米诺环素的糊剂进行药物治疗。牙齿用矿物三氧化物凝聚体封闭，并用复合树脂修复。18个月后取得了满意的效果。患者无症状，影像学证据显示透影区完全消失、牙本质壁持续增厚、根尖闭合且牙根长度增加。
